In the extended structure, N\u2014H...O hydrogen bonds connect the molecules into [100] chains and weak C\u2014H...O interactions and pairwise C\u2014H...\u03c0 interactions consolidate the packing. A Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H...H (57.6%), C...H\/H...C (24.2%), and H...O\/ O...H (13.8%) contacts. Evaluation of the electrostatic, dispersion and total energy frameworks indicates that the cohesion of the crystal largely depends on dispersion energy contributions.\n                  <\/jats:p>","DOI":"10.1107\/s2056989026005049","type":"journal-article","created":{"date-parts":[[2026,5,14]],"date-time":"2026-05-14T07:34:41Z","timestamp":1778744081000},"page":"670-673","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":1,"title":["Synthesis and structure of (\n                    <i>Z<\/i>\n                    )-2-(ethoxymethylidene)-8-methyl-2,3,4,9-tetrahydro-1\n                    <i>H<\/i>\n                    -carbazol-1-one"],"prefix":"10.1107","volume":"82","author":[{"given":"Makuteswaran","family":"Sridharan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9896-186X","authenticated-orcid":true,"given":"Aravazhi Amalan","family":"Thiruvalluvar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2026,5,15]]},"reference":[{"key":"hb8217_bb1","unstructured":"Bruker (2002).
